Abstract
Atrial natriuretic peptide (ANP), the C-terminal peptide comprising residues 99–126 of the pro-ANP hormone, has been studied for 3 decades for its cardiovascular effects. Recent reports suggest that it plays a significant role in modulation of the immune system. Immune cells, including macrophages, dendritic cells, and T lymphocytes, express receptors for ANP. ANP plays a significant role in shaping the early immune response to environmental antigens and may play a critical role in the interaction between cells of the innate and adaptive immune systems; it also appears to be involved in polarizing the immune response to allergens. Thus, ability to alter the magnitude of natriuretic peptide receptor A (NPRA) signaling could be exploited to develop therapeutics for several allergic diseases, including asthma. This report will review and critically evaluate the role of the ANP pathway in asthma and inflammation.
